I am cooking sunchokes for the first time tonight. I want to make a puree with some cream. All the recipes I find require peeling the sunchokes, but I saw Gordon Ramsay recommend to not peel them, saying all the flavor is in the skin. Do you peel them or not? If you don't, do you have to somehow strain the puree to get rid of the skin bits or does the skin get pureed along with the sunchokes? Thanks!
